Scary factor: Marlin’s wife disappears in opening scene, the (offscreen) victim of a barracuda; throughout: much peril, many close escapes, but the pace is good, nothing lasts for very long so you should be able to sail right through. In the fish tank Nemo has the threat of a ‘fish-killer’ little girl hanging over him, and takes part in escape plans in which he risks being sucked into the filtration system rotating blades. No real violence or gore. (Dory is accidentally smacked in the nose once and a little blood drips out, that’s it.)

Most scary: a huge shark chases Marlin and Dory, chase ends with underwater mines exploding (The shark scene occurs right after Marlin meets Dory, if you want to skip it.)

Next most scary: a creepy anglerfish chases them: see picture at the end of this review. Anglerfish scene occurs after they chase the sinking swim mask into the darkest deep, if you want to skip it. Be sure, though, to watch to the very end of the credits, when the anglerfish gets his comeuppance.

Intense scenes: my daughter was bugged by the jellyfish scene. The jellyfish are rather passive, they don’t even seem sentient, but it is really creepy how they float in and surround the fish. Big suspense. Another one which bothered her was the scene inside the whale, when Marlin loses all hope. There isn’t anything overtly scary, but the intense emotions troubled her a little.
